SBM PFW impact crusher can be used in medium crushing and fine crushing stage and it is suitabtle to crusher the soft materials whose Moh is <5. It is widely used in metallurgy, mining, cement, chemical, refractory materials and ceramic industries, as well as the highway construction, water conservancy project, building sand gravel, mechanism processing and so on.

Structure:

Fix with screws: screw is shown on the surface, easy to damage, and screw will accept larger shear force , once cut will cause serious accidents.

Clamp fixed: From the side inserted into a groove in the rotor plate hammer, on both ends of the clamp pressure. But this way of fixed plate hammer not strong enough, the work medium plate hammer easy to loose. (Need to welding, pressure plate is easy to wear and not easily be replaced)

Wedge fixed: The wedge will be fixed on the rotor plate hammer. In the working process, under the action of centrifugal force, the faster the fixed way can guarantee the rotor speed, fixed plate hammer and stronger. It is easy to change. This is a better fixed way and all countries are adopting this kind of fixed mode.
